ABSTRACT
Ecosystem services provided by urban green areas have been recognised to an increasing degree following the turn of the millennium. Urban trees in particular provide urban dwellers with a variety of ecosystem services. This chapter argues for the recognition of both the ecosystem services and disservices of urban trees. It starts with concrete cases of disservices and proceeds towards more abstract methodological issues. First, the chapter presents a typology of disservices based on available examples. Second, it outlines different methods and data sources used to identify and analyse disservices. Third, the chapter discusses criteria for frameworks aimed at aiding the assessment of the disservices. It is argued that in the long term, successful urban planning and management should be based on integrated knowledge of services and disservices as well as continuous communication and interaction aimed at increasing public acceptance and policy awareness of different aspects of urban trees and urban biodiversity.
